ABSTRACT:
A structure for high voltage bearable transformers is used to electrically connect with backlight driving circuits of liquid crystal display devices. The structure for high voltage bearable transformers is comprised of at least one main bobbin, at least two sets of primary windings, and at least one set of secondary windings. The main bobbin is divided into a primary bobbin and a secondary bobbin. The primary windings are wound on the primary bobbin. The secondary windings are wound on the secondary bobbin. The structure of the high voltage bearable transformer has a tolerance for high voltage, and may connect to several driving units to export several high voltage outputs for driving cold-cathode fluorescent lamps simultaneously.
